lol i have a flowmaster on my 99 Blazer,sounds mellow. i got it off ebay,it was new and only used for mock up got it for 15 bucks + s/h.It has a 3" inlet and 3" outlet. It would be louder if you either gutted or removed the converters,but its illegal,and would cause the check engine light to come on.I did notice some gain,and gas mileage was slightly better,maybe 1/2 to 1 mile per gallon better. Dont expect it to be loud,like a flowmaster on a v8 pick up.
